BACKGROUND Computed tomography (CT) scan is one the most useful devices in chest imaging. CT scan can be used in mediastinal abnormality, lungs, and pleural evaluations. According to the high prevalence and different causes of pulmonary nodules, we designed this study to evaluate the prevalence and the types of pulmonary nodules in noncancerous patients who underwent chest multi-detector CT (MD...

Title: Pathways for definitive diagnosis of solitary pulmonary nodule: a multicentre study in 18 French districts

A 68-year-old man had multiple left pulmonary nodules with serum positivity for proteinase 3 anti-neutrophil cytoplasmic autoantibody (PR3-ANCA) and negativity for cryptococcal antigen (Picture 1). We initially regarded him as having granulomatosis with polyangiitis (GPA). He subsequently underwent a video-assisted surgical lung biopsy for the diagnosis (Picture 1, arrowheads). Hematoxylin and ...

The Existing approach consist of CAD scheme with Virtual Dual Energy. CXRs where ribs and clavicles are suppressed with massive-training artificial neural networks (MTANNs) To reduce rib-induced FPs and detect nodules overlapping with ribs, we incorporated the VDE technology in our CADe scheme. The VDE technology suppressed rib and clavicle opacities in CXRs while maintaining soft-tissue opacit...

OBJECTIVE Pulmonary metastasectomy is beneficial in select patients. The sensitivity of (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) for pulmonary metastasis is unknown. The aims of the study were to determine the accuracy of FDG-PET in detecting pulmonary metastasis and identify factors affecting sensitivity. METHODS All patients undergoing metastasectomy from September 20...

Pulmonary nodule detection is essential to reduce the mortality of lung cancer. One-stage methods have recently emerged as high-performance and lower-power alternatives two-stage methods. However, it difficult for existing one-stage networks balance sensitivity specificity. In this paper, we propose an end-to-end mechanism combined with a channel-wise attention based on 3D U-shaped residual net...

To describe the features and clinical implications of computed tomography (CT), positron emission tomography (PET), and percutaneous needle aspiration biopsy (PCNB) in pulmonary nontuberculous mycobacterial (NTM) disease manifesting as a solitary nodule, mass, or mass-like consolidation mimicking malignancy.Among a cohort of 388 patients with NTM pulmonary disease, 14 patients with clinically a...

Pulmonary arteriovenous malformations are rare congenital abnormal connections between the pulmonary arteries and veins. The patients are usually asymptomatic [1]. Although their aetiology is unclear, it is presumed that genetic abnormalities constitute a predisposition [1, 2]. An arteriovenous malformation might cause serious complications if it remains undiagnosed and untreated [3]. We report...
